Top Mount Base BSA Colt Rem, 40AM Black, Poly Bag Review

The Top Mount Base BSA Colt Rem, 40AM Black, Poly Bag Made a Bold First Impression

The Top Mount Base BSA Colt Rem, 40AM Black, Poly Bag isn’t exactly the sexiest piece of tactical gear, but it’s arguably one of the most essential for turning a good rifle into a great rifle. It’s a humble, one-piece aluminum base designed to provide a secure platform for mounting optics on a wide range of firearms. Manufactured by BSA, this base promises unwavering strength and a cross-lock design for ring compatibility.

I was in the market for a reliable base for my aging Remington 700. The factory-installed bases had seen better days, and accuracy had begun to suffer. I was looking for something solid, dependable, and preferably affordable without sacrificing quality.

Upon receiving the Top Mount Base BSA Colt Rem, 40AM Black, Poly Bag, my initial thought was, “This is… utilitarian.” It arrived in a simple poly bag, no frills, just the base and mounting screws. The aluminum felt solid in my hand; the black finish was even and consistent. Compared to the flimsy, two-piece bases I’d used in the past, this felt like a serious upgrade. I was cross-shopping this against a Leupold Mark 4 base and a Weaver Grand Slam base. The Leupold was significantly more expensive, and while the Weaver had a nicer finish, the BSA seemed just as robust at a more palatable price point.

My first impression was cautiously optimistic. It wasn’t love at first sight, but the Top Mount Base BSA Colt Rem, 40AM Black, Poly Bag looked like it could deliver on its promise of stability and versatility. Only real-world testing would tell.

Real-World Testing: Putting Top Mount Base BSA Colt Rem, 40AM Black, Poly Bag to the Test

First Use Experience

My first test was at my local shooting range. I mounted the Top Mount Base BSA Colt Rem, 40AM Black, Poly Bag on my Remington 700 .30-06, carefully following the torque specifications. The installation was straightforward. No filing or fitting was required. The base sat flush against the receiver. I then mounted a trusted Vortex Viper PST Gen II 3-15×44 scope. The cross-lock design of the base made ring placement easy and secure.

The range day was blustery and cold. The wind was whipping around, making for less-than-ideal shooting conditions. Despite the conditions, the rifle, now fitted with the BSA base, held zero consistently. I fired about 60 rounds, and the base remained rock solid. There were no signs of shifting or loosening. Even under recoil, the scope stayed put.

The ease of installation impressed me, especially given the variety of rifles it’s compatible with. The lack of issues after the first use was a promising sign.

Extended Use & Reliability

After several months of use, the Top Mount Base BSA Colt Rem, 40AM Black, Poly Bag continues to perform admirably. My rifle has seen several trips to the range and even a weekend hunting trip in moderately rugged terrain. The base shows no signs of wear or corrosion. The finish is still intact.

Maintenance is minimal. A quick wipe down with a lightly oiled cloth after each use is all it takes to keep it in good condition. I’ve removed and reinstalled the scope several times for cleaning and transport. The BSA base has maintained its integrity. It hasn’t lost zero.

Compared to some of the cheaper bases I’ve used in the past, this is a night-and-day difference. Those older bases tended to loosen over time. The BSA base has provided unwavering stability. It has definitely exceeded my expectations for a base in this price range.
